AI Technical Summary

Technical Problem

When the exhaust holes of the existing lawn mower transmission are tilted or inverted, it may cause lubricant to flow out, and when external dust and water vapor are stopped, it may enter the transmission, causing lubricant to fail and parts to rust.

Method used

A transmission exhaust device is designed, and a ventilation plug is installed through the fixing part, and a dust-proof layer and wear-resistant layer are installed on the outside to prevent dust and water vapor from entering, avoid lubricating oil failure and parts corrosion, and at the same time, through adjustment holes and rebounds The component adjusts the gas discharge to ensure the service life of the ventilation plug.

Benefits of technology

Effectively prevent external dust and water vapor from entering the transmission, extend the service life of the transmission, and reduce wear of the ventilation plug through the wear-resistant layer, and improve exhaust efficiency.

Abstract

The gearbox exhaust device comprises a ventilation plug, a fixing part, a wear-resistant layer and a dustproof layer, the bottom of the ventilation plug is arranged in a ventilation hole formed in a gearbox through the fixing part, a mounting groove is formed in the outer side of the ventilation plug, an exhaust hole communicated with the ventilation plug is formed in the mounting groove, and the dustproof layer is arranged in the ventilation plug. The dustproof layer is arranged outside the ventilation plug, the wear-resistant layer is arranged between the ventilation plug and the dustproof layer, the ventilation plug is temporarily fixed to a ventilation hole formed in the gearbox through the fixing part, and through the dustproof layer, external dust particles and water vapor can be prevented from entering the gearbox from the ventilation plug when the gearbox stops working; the problems that lubricating oil in the gearbox loses efficacy, and internal parts are rusted are solved, the service life of the gearbox is prolonged, the abrasion-resistant layer is arranged, when the dustproof layer is operated, the outer portion of the ventilation plug cannot be abraded, and the service life of the ventilation plug is prolonged.
